Most of the websites which propose Macintosh icons to download, provide them in archives using SIT/HQX packed file format. This file format is widely used by Macintosh users.

To uncompress these archive files under Windows, you need a specific tool: StuffIt Expander for Windows. Click to visit StuffIt website and download the software. This how-to procedure has been designed for version 9.0 of StuffIt Expander.

You can either purchase the full version which is required to compress files and create SIT archives or download the "StuffIt Standard Free Trial". They both contain the StuffIt Expander portion which is free and permit to extract files from SIT archives.

We
recommend you to remove the association with MacBinary (BIN) files because
IconWorkshop supports this type directly.
